Product details
Overview
TLE2024AMFKB from Texas Instruments is a quad-channel, precision bipolar operational amplifier optimized for low-power, high-speed signal conditioning in single-supply (5V) and split-supply (±15V) configurations. It delivers 2 MHz unity-gain bandwidth, 0.65 V/µs slew rate, 100 µV max input offset voltage, 300 µA max supply current, and rail-to-rail input capability down to the negative rail - enabling accurate amplification of low-level sensor signals in industrial transmitters and instrumentation.
For engineers reviewing the TLE2024AMFKB datasheet, TLE2024AMFKB pinout, TLE2024AMFKB application, or TLE2024AMFKB equivalent, this page provides verified electrical specifications, military-grade temperature performance (–55°C to +125°C), SOIC-16 package details, phase-reversal protection behavior, and validated alternative op-amps for design continuity and sourcing resilience.
Technical Context
The TLE2024AMFKB uses Texas Instruments' proprietary complementary bipolar process with isolated vertical PNP transistors, enabling significantly improved unity-gain bandwidth and slew rate over legacy precision op-amps like the OP21. Its bias circuit ensures exceptional parameter stability across time and temperature.
This architecture supports stable DC precision (6.5 V/µV open-loop gain, 136 dB) while maintaining AC performance (2 MHz GBW, 46° phase margin) and robust operation in demanding environments - including flow and pressure transmitter front-ends where input common-mode range must include the negative rail and output must drive 10 kΩ loads without saturation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-channel signal conditioning without discrete op-amp duplication. |
| Supply Current | 300 µA max - allows battery-powered or energy-constrained systems to integrate precision amplification without compromising runtime. |
| Unity-Gain Bandwidth | 2 MHz - supports accurate amplification of medium-frequency sensor outputs (e.g., 4–20 mA loop receivers, strain gauge bridges). |
| Slew Rate | 0.65 V/µs - ensures faithful reproduction of fast transient signals up to ~300 kHz without distortion. |
| Input Offset Voltage | 100 µV max - minimizes DC error in precision analog front-ends, critical for sub-mV-level measurements. |
| Common-Mode Input Range | Includes negative rail (0 V at 5V supply) - permits direct interfacing with grounded-sensor configurations without level-shifting. |
| Operating Temperature | –55°C to +125°C - qualified for military, aerospace, and under-hood automotive applications requiring extended thermal reliability. |
Pinout & Package
Package: DW (SOIC-16), 16-pin small-outline integrated circuit with standard 1.27 mm pitch and gull-wing leads. RoHS-compliant, surface-mountable, and thermally optimized (RθJA = 62.7 °C/W).

| 11, 13 | VCC– | Negative power supply terminal - accepts down to –20 V (dual) or ground (single-supply); shared across all channels. |
| 8, 9 | NC | No-connect pins - left unconnected per TI mechanical specification for DW package. |
Key Features
| Feature | Design Value |
|---|---|
| Phase-reversal protection | Prevents catastrophic output inversion when input falls below VCC– - essential for fault-tolerant sensor interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA227UA | Single-channel, 8 MHz GBW, 2.3 V/µs slew rate, 10 µV max VIO, SOIC-8 package. | Higher speed and lower offset, but single-channel and not qualified for –55°C operation. | Preferred for high-accuracy, single-channel lab equipment where speed >2 MHz is required and military temp range is unnecessary. |
| LMC6064IMX/NOPB | Quad CMOS op-amp, 0.12 MHz GBW, 0.035 V/µs slew rate, 0.25 mV max VIO, SOIC-14 package, rail-to-rail I/O. | Ultra-low input bias (2 fA), but much lower bandwidth and no phase-reversal protection. | Best suited for ultra-high-impedance sensor interfaces (e.g., photodiode transimpedance) where speed is secondary to input leakage. |
Compared with OPA227UA and LMC6064IMX/NOPB, the TLE2024AMFKB uniquely balances military-temperature operation, quad-channel integration, phase-reversal immunity, and 2 MHz bandwidth - making it irreplaceable in ruggedized multi-sensor analog front-ends where reliability and functional safety are non-negotiable.

FAQ
What is the maximum operating temperature range for the TLE2024AMFKB?
The TLE2024AMFKB is rated for continuous operation from –55°C to +125°C, meeting MIL-PRF-38535 requirements for Class B military-grade devices. This full-range specification is confirmed in Section 6.2 of the official TI datasheet (SLVSJD7A) and applies across all electrical parameters unless otherwise noted in the "M-suffix" characterization tables.
Does the TLE2024AMFKB support single-supply operation at 5V?
Yes, the TLE2024AMFKB is fully specified for 5V single-supply operation. Its common-mode input range extends to the negative rail (0 V), and output swing reaches within 0.7 V of both rails under 10 kΩ load - enabling direct interface with microcontrollers and ADCs without level-shifting circuitry. Electrical characteristics at 5V are detailed in Section 6.7 of the TI datasheet.
What does "phase-reversal protection" mean for the TLE2024AMFKB?
Phase-reversal protection prevents the output from inverting polarity when either input is driven below the negative supply rail (e.g., during ESD events or sensor disconnect). Unlike unprotected op-amps, the TLE2024AMFKB maintains predictable output behavior - critical for fail-safe operation in industrial transmitters where input faults must not trigger erroneous control actions.
Is the TLE2024AMFKB pin-compatible with other TLE2024 variants like TLE2024CDW?
No - the TLE2024AMFKB uses the DW (SOIC-16) package, while TLE2024CDW also uses SOIC-16, but the "M" suffix denotes military temperature screening and tighter parameter limits (e.g., 100 µV max VIO vs. 750 µV for TLE2024ACDW). Pinout is identical, but electrical specs and qualification differ; substitution requires validation against system-level temperature and precision requirements.
What is the typical input voltage noise density of the TLE2024AMFKB at 1 kHz?
The TLE2024AMFKB has a typical input voltage noise density of 15 nV/√Hz at 1 kHz, as specified in Section 6.6 (AC specs) of the TI datasheet. This value remains consistent across temperature and supply conditions, supporting low-noise signal conditioning in precision measurement applications such as laboratory instrumentation and sensor front-ends.
